So they got on a train and rode through a canyon which, as the name suggested, was everywhere lined with great boulders of all shapes and sizes. Here a roaring torrent would cleave a way down to the bottom of the canyon, while there an abrupt wall of rock defied the elements and all things else to maintain its stand.

At Tungsten, the end of the trail, the scouts visited the district where this metal is mined. When they were through with the visit, Mr. Gilroy told the girls that Boulder County’s record of income from tungsten alone was more than five million dollars a year.

The State University at Boulder was visited upon the return of the scout tourists to that city. Here the girls learned that the campus covered over sixty acres of ground, and that the university boasted of twenty-two splendidly equipped buildings, equal to any in the world. It also had a library of its own that numbered about eighty-three thousand volumes. The value of the buildings approximated one million, seven hundred and fifty thousand dollars.

“It doesn’t seem possible, when you look around at what this place is—or seems to be!” exclaimed Ruth.

“Which goes to prove that appearances are not necessarily harmonious with facts,” returned Mrs. Vernon, smilingly.

When they met Tally, who was waiting at the place appointed, Julie asked, “Where do we go from here, Gilly?”

“We’ll follow Tally, as he seems to have a plan back of that grin,” returned Mr. Gilroy.

Every one turned to look at Tally, who in turn seemed quite taken by surprise, as he said, “Tally no plan!”

“Ah, Tally! Will you never understand my winks!” sighed Mr. Gilroy. “I wanted you to help me out while I evaded an issue with these dreadful Scouts.”

“Um, Tally glad to if Mees’r Gilloy onny tell him.”
